Project summary

The integration of waste heat from industrial processes has been identified as a major research area in the EU strategy on heating and cooling. In fact, the waste heat potential of combined heat and power stations (CHP) or energy-from-waste plants is well understood and district heating (DH) networks in markets with varying maturity across the world utilise this typically high-grade type of waste heat. The MEMPHIS project builds upon previous research from the project partners and other researchers in the DH sector and focusses on the potential and feasibility of supplying urban areas with low-grade waste heat

A transparent, publicly accessible and internationally applicable methodology helps national heat policy makers to promote the usage of low-grade waste heat across a country. Local authorities, city planners and developers will be able to use the tool to identify maximum size and diversity of waste heat potential at local level. This can improve decentralised energy master planning for new DH or future-proofing strategies for existing and/or expanding networks. The methodology will be applied at three example cities in Germany (City of Mannheim),
United Kingdom (City of Edinburgh) and Austria.

Deliverables / Outcomes

  • a generic methodology using open data to assess waste heat potential from industry and service sector on a city district level
  • a generic methodology using open data to assess heat potential from sewage water flows in cities

  • application of the new methodology to three representative cities / regions in Germany, Austria and the United Kingdom
  • an analysis of the transferability of the methodology to other IEA DHC member countries.
